When seeking content multiple times with a watch party the server now appears to crash. This is repeatable and unfortunately made a mess of trying to watch movies with friends.

Most clients at the time were either plex app or plex web, streaming original quality with only audio transcodes and a ipad being transcoded with nvenc.

I managed to replicate the issue again today twice and have the following log/dmp files associated with the crash. This is 3 clients, 2 web (firefox/edge) and plex app all under my own account. All I did was seek the file multiple times, first time i tried it on a long 2hr movie it took 3 seeks to crash, on a tv show like this log shows it took a few more.

had previously watched movies on watch together with plexmediaserver_1.23.0.4438-5eef0fd80 and had no issues like this, outside of other issues I have on my server with hw transcoding there has certainly been looping issues in the past which cause peopel to reseek/play/pause but nothing crashed the server before!

Well since rolling back to 1.23.0.4438 as I assumed it worked fine, I can reproduce the same issue. It seems harder to do but crashing while skipping on the time line does infact end up crashing the server too!
